Thanks again everyone! I contacted the vet a few days ago and they will not let me have copies of his results until we pay the remaining balance of the bill. As soon as I can, we will be finding someone else to give us answers...the right way.
I have measured his water intake for about a week now and between the time we wake up and when we go to bed, he drinks around 3 cups of water every day. I've watched his drinking habits and noticed that he mainly drinks after he eats and after he sleeps.
I do have a crazy question about urine in a cushings dog. I've read that dogs with cushings have dilute urine? What exactly does this mean? Is their urine clear and no scent?? I read that somewhere, but wanted to check if I'm correct.
